Abstract
Abstract A toy phonograph arranged in a semi-cylindrical housing which is divided into upper and lower compartments. The motor is disposed at a corner of the casing. A turntable is mounted for rotation by the motor on a platform of corresponding semi-cylindrical shape which is supported by one corner on a shaft concentric with the shaft of the motor for movement into and out of the lower compartment. The sound reproducing mechanism is disposed in the upper compartment. The phonograph is provided with automatically acting means for immobilizing the platform when disposed within the lower compartment; the means being manually releasable to permit withdrawal of the platform from the lower compartment.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
225 words
In a toy phonograph comprising a casing of substantially semi-cylindrical contour defining a curved wall, a straight wall portion, and a corner; said casing divided into an upper and a lower compartment by a partition substantially normal to the cylindrical axis of the case; a motor mounted at said corner of said casing, said motor having a shaft parallel to the cylindrical axis of said casing, said shaft extending into said lower compartment and adapted to be operably engaged with a turntable; said turntable including a turntable shaft; a platform for supporting said turntable on said turntable shaft at a midpoint of said platform, said platform defining a straight edge and having first and second corners, said first corner secured to a pivot shaft concentric with the shaft of said motor for pivotally mounting said platform for movement into and out of said lower compartment; a pickup arm movably supported in said upper compartment and having a stylus connected to said pickup arm at one end thereof; a speaker and means moving said pickup arm; said partition having a cut-out portion extending inwardly from the plane of said straight wall portion such that said turntable shaft is adapted to extend through said cut-out portion into said upper compartment and such that said stylus is adapted to extend through said cut-out portion inTo said lower compartment.
Claim 2
Dependent Claim
225 words
In a toy phonograph comprising a casing of substantially semi-cylindrical contour defining a curved wall, a straight wall portion, and a corner; said casing divided into an upper and a lower compartment by a partition substantially normal to the cylindrical axis of the case; a motor mounted at said corner of said casing, said motor having a shaft parallel to the cylindrical axis of said casing, said shaft extending into said lower compartment and adapted to be operably engaged with a turntable; said turntable including a turntable shaft; a platform for supporting said turntable on said turntable shaft at a midpoint of said platform, said platform defining a straight edge and having first and second corners, said first corner secured to a pivot shaft concentric with the shaft of said motor for pivotally mounting said platform for movement into and out of said lower compartment; a pickup arm movably supported in said upper compartment and having a stylus connected to said pickup arm at one end thereof; a speaker and means moving said pickup arm; said partition having a cut-out portion extending inwardly from the plane of said straight wall portion such that said turntable shaft is adapted to extend through said cut-out portion into said upper compartment and such that said stylus is adapted to extend through said cut-out portion inTo said lower compartment.
Claim 3
Dependent Claim
73 words
The toy phonograph of claim 1, including cooperating means disposed in said upper compartment and adapted to cooperate with said platform for automatically inter-engaging said platform upon movement of said platform into said lower compartment to prevent movement of said platform out from said lower compartment, and manually operable means extending to the exterior of the casing for releasing said cooperating means for allowing movement of said platform out from said lower compartment.
Claim 4
Dependent Claim
144 words
The toy phonograph of claim 2, wherein said cooperating means comprises an upright arcuate wall portion along said edge of said platform, said upright wall portion extending inwardly from said second corner, said upright wall portion having at one end a detent notch formed in its upper edge contiguous to the straight edge of said platform and a downwardly curving cam edge at its other end, and a bar having a depending detent nose pivotally supported in said upper compartment in position to have its inner end engaged by such cam edge portion upon movement of said platform inwardly into said lower compartment to thereby have said detent nose engaged in said detent notch, and wherein said means releasing said cooperating means includes a pin movably mounted in said casing and extending outwardly thereof, said pin resting on the inner end of said bar.
Claim 5
Dependent Claim
45 words
The phonograph of claim 3, wherein a normally open switch connectable in the circuit of the said motor is mounted in said upper compartment, and wherein means are provided on said platform for closing said switch when said platform is moved into said lower compartment.
Claim 6
Dependent Claim
86 words
The phonograph of claim 4, wherein said normally open switch comprises a pair of parallel spring elements secured in insulated space relation to one another by one end and lying in a plane substantially parallel to the plane of said platform, and means are provided on said platform for moving one of said elements into contact with the other when said platform is moved into said lower compartment, whereby said switch is closed and remains in closed position while said platform remains in said lower compartment.
Claim 7
Dependent Claim
78 words
The toy phonograph of claim 5, wherein an upright wall is provided along the straight edge of said platform and said means for moving said elements comprises an inwardly extending pin on said upright wall, said pin adapted to extend into said upper compartment when said platform is moved into said lower compartment to thereby engage the adjacent one of said elements and move it into contact with the other of said elements, to thereby close said switch.
